Four grams of O2 gas (molecular weight 32 g/mol) is compressed from an initial state of Pi = 1.30×105Pa, Vi = 4.50 L to a final state of Pf = 1.10×105 Pa, Vf =1.9 L along a path that forms a straight line on a PV diagram. (a) What is the final temperature? (b) What is the work done on the gas?
A spacecraft is fueled using hydrazine (N2H4; molecular weight of 32 grams per mole [g/mol]) and carries 1,648 kilograms [kg] of fuel. On a mission to orbit a planet, the fuel will first be warmed from negative −176 degrees Fahrenheit [°F] to 87 degrees Fahrenheit [°F] before being used after the long space flight to reach the planet. The specific heat capacity of hydrazine is 0.099 kilojoules per mole kelvin [kJ/(mol K)]. If there is 500watts [W] of power available...
